摘　　要：多数学者认为准噶尔盆地中部车莫古隆起对油气起着重要的控制作用,在其波及区发育原生油气藏和掀斜调整型油气藏,油气勘探潜力评价不高。通过构造演化分析,明确了车莫古隆起主要发育形成在白垩系(K)地层沉积前,至晚白垩纪(K2)初已基本被埋藏,掀斜改造成单斜状构造形态;落实了K2-第四纪(Q)为油气主成藏期,制作了K1末成藏期的古构造图,并与车莫古隆起和现今构造进行对比,认为仅莫西庄地区油气成藏受车莫古隆起控制,发育原生油气藏和掀斜调整型油气藏,大部分地区不受其控制,原生油气藏未被破坏,并指出征1-沙1鼻状构造带和莫西庄地区是油气富集区。The most of scholars believed that Chemo palaeohigh played an important controlling role in oil and gas in central Junggar Basin.The primary and tilted adjustable reservoirs were developed in the affected area.The evaluation for oil and gas exploration potential was not high.Through analysis of tectonic evolution,it was clarified that Chemo palaeohigh was formed mainly before Cretaceous(K)formation deposition,and it was buried basically at initial stage of late Cretaceous(K2).It was tilted into monoclinal structure.It was clarified that K2-Q was the main oil and gas accumulation period.Paleotectonic map of accumulation period at the end of K1 was developed and compared with Chemo palaeohigh and the current structure.It is considered that oil and gas accumulation in Moxizhuang Area is only controlled by Chemo palaeohigh,where primary and tilted adjustable reservoirs are developed.Most of the other areas are not controlled by it.Primary oil and gas reservoirs are not damaged.It is pointed out that Zheng 1-Sha 1nose-like structure belt and Moxizhuang Area are the areas of oil and gas enrichment.
